BRUSH-MACHINE.

SPECIFICATION forming part of Letters Patent No. 530,151, dated December4, 1 894. Application filed November 30, 1891- Serial No. 413,521. (Nomodel.)

To all whom it may concern:

Be it known that I, MOCLINTOOK YOUNG, of Frederick, county of Frederick,and State of Maryland, have invented a new and useful ImprovementinBrush-Machines, of which the following is a specification.

The machine forming the subject of this invention is designed to seat aU-shaped staple astride a bunch or wisp of fiber, bend or double thefibers through the staple to form a tuft, and then carry the tuft andstaple into a hole in the brush-block or body, driving the legs of thestaple point foremost, firmly into the wood. It embraces as its leadingfeatures grooved guides for the staple, a reciprocating staple-drivingblade, a slotted bed on which the fiber is sustained and by which it isdoubled or folded around the descending staple. It also embraces meansfor sustaining and feeding the staples and supporting the brushblock.

In the accompanying drawings,-Figure 1 represents a side elevation of myimproved machine, a portion of the foot-lever being broken away toexpose other parts to view. Fig. 2 is a front elevation of the machine.Fig. 3 is a front elevation on an enlarged scale of the upper portion ofthe machine. Figs. 4, 5 and 6 are sections taken respectively on thelines 4-4, 5 5 and 66'of thepreceding figures, and illustrating thedetails of the staple guiding and driving devices.

Referring to the drawings,-A represents a rigid frame, which may be ofany suitable form adapted to sustain the operative parts hereindescribed, which, as represented in the drawings, consist of a standardhaving an expanded base or foot, and an overhanging upper end.

B represents a horizontal bed or table bolted or otherwise fixed to theframe and extending beneath its overhanging end. This bed or table Bisdesigned to receive and sustain en masse the fibers to form the tufts.This bed is provided with a suitable box or receptacle 0, open in oneside, in which the fibers, cut to the required length, are laidhorizontally, so that they may be worked out by hand in sheet formtoward the projecting end of the table, which at its end is providedwith a vertical slot or opening to admit of the tuft being carrieddownward therethrough.

To the overhanging end of the main-frame are firmly fixed twoguide-plates D and D, having vertical parallel edges provided withvertical grooves d d, to receive and guide the legs of the staple. Theseguide-plates D D, are continued downward through and beyond the bed B,and terminate in arms or points d, which being seated on the brush-blockdirect the tuft and staple to their place therein. Above the level ofthe table B, the guides D D, have their front walls cut away, as shownat (1 in order to produce an opening through which the staples may beinserted point foremost in a downward direction into the guidinggrooves, in the manner indicated in Figs. 3 and 4t.

It will be observed that an open horizontal space exists between theunder side of the guide I) and the tuft-supporting table B, so that thefibers may be spread out in sheet form and Worked by hand horizontallyunder the guide D and against the vertical face in such position thatthose required to form a tuft will lie immediately beneath the staple inthe guide, so that when the staple is driven downward .it will straddleor embrace the required number of fibers to form the tuft and carry thesame downward at the middle through the opening in the table B, wherebythe ends of the fibers are folded or doubled upward around and above thestaple, the ends of the fiber projecting upward while the points of thestaple extend downward below them.

For the purpose of driving the tuft and staple I provide the blade G,bolted or otherwise fastened to a plate, H, arranged to reciprocate invertical guides on the overhanging end of the main-frame. The plate H isoperated by a pitman I, the lower end of which encircles a large boss onthe plate while the upper end is jointed to one end of the lever J,which is mounted on a horizontal journal or pivot K, on the main-frame,and curved downward and forward in such shape as to admit of its beingreadily vibrated by the foot of theloperator applied to the foot-piecej, at its lower end. form at will, but I recommend the form shown in thedrawings, as being convenient and serviceable. it ispreferably formedwith a weight, j, on the rear side, as shown. When This lever J, may bevaried in' formed as shown, the lever hangs normally in the positionindicated in Fig. 1, holding the driving blade G, in an elevatedposition. After being operated by rearward pressure of the foot itreturns automatically to this position.

Below the table B is mounted a bed-plate L, intended to sustain orsupport the brushblock, previously bored, in position to receive thetufts and staples as they are driven downward through the overlyingguides. The bedplate L may be sustained in any suitable manner but Icommonly provide it with a hori zontal journal Z, seated in cars on theunder side of the bed B, so that it may be tipped or rocked according tothe angle at which the tufts are to be inserted in the brush-block. Iprovide the table with a rigid outreaching arm Z to which there isjointed an arm 1 provided with notches Z, and arranged to engage a rigidstop Z whereby the table may be locked at different inclinations.

The feeding of the staples into the guides may be effected by hand, asindicated in Fig. 3, without the assistance of feeding devices of anykind, but in order to facilitate the operation I prefer to provide, asshown in Figs. 1 and 2, a horizontal guide-bar M, sustained by a lateralarm N, with one end presented toward the feed openings d To make use ofthis guide the staples are placed astride of the same in series andpushed forward in such manner that at each descent of the drivingbladeG, the foremost staple will be carried downward thereby through theguide. The arm M, is preferably pivoted to the frame at m, and fastenedby a clamp screw m passing through a curved fixed arm m Thisarrangementadmits of the guide being turned upward out of the way when it is not tobe used, as indicated by dotted lines in Fig. 3.

It will be observed that the present machine is not intended to form thestaples which it drives. I propose to make use of staples such as arecommonly sold in the market having pointed and barbed legs of suchstrength that they may be driven into the wood without bending orcrossing so that the bight of the tuft will be confined between the legsof the staple and the bottom of the hole. I believe myself to be thefirst to construct a ma chine adapted to thus insert the staples, and itis to be understood that the details of the parts both as to form andarrangement may be modified, provided they are adapted to operateessentially as described.

Having thus described my invention, what I claim is- 1. In a brushmachine, a staple guide adapted to permit the insertion of a completedstaple, and a reciprocating blade to drive the staple, in combinationwith a fiber support extending across the path of the driving blade andhaving an opening for the passage of the staple and fiber, and a supportfor the brushblock.

2. The grooved guide to receive the legs of a staple and provided with alateral opening to admit the staple, in combination with the drivingblade arranged to slide in said guide, and a fiber support extendingacross the path of the driving blade and having an opening for thepassage of the doubled fiber and the staple therethrough.

3. In a brush machine, the combination of a guide to receive the legs ofa staple, a reciprocating staple-drivin g blade, a staple su pportarranged to guide the staples points forward beneath the blade, and anunderlying fiber support having an opening for the passage of the fibersand staples therethrough.

4;. In a brush machine, the grooved staple guide, the reciprocatingdriving blade, the fiber support extending across the path of the bladeand having an opening therethrough, and the staple-supporting arm hingedto turn away from its operative position.

5. In combination with a brush-block support and an overlying fibersupport, having an opening therethrough, a staple guide, a drivingblade, and a pendulous lever, coupled with and adapted to operate thedriving blade, substantially as shown.

6. In a brush machine, and in combination with a driving blade, a stapleguide adapted for the introduction of the staple, points foremost, and afiber support having a passage to permit the lateral introduction of thefiber beneath the descending staple, and with an opening therethroughfor the passage of the staple and its contained fiber: whereby thestaple is caused to separate the tuft from the remaining fiber, the tuftdoubled, and the tuft and staple driven into the brush block.

In testimony whereof I hereunto set my hand, this 8th day of October,1891, in the presence of two attesting witnesses.

MCOLINTOOK YOUNG.
